I love the colour scheme used on the London Underground. Everything; maps, posters, artwork, mosaics. Anything officially connected to the tube explodes with primary and brightly saturated secondary and tertiary colours. Even the interiors of the trains on the different tube lines. I especially like the green on the District line.
